'Application mea my s, 1910. serial No. 570,051.

To 'all 'whom 'it may concern:

Be it known that I, CHARLES A. SAYRE, a citizen of the United States, 4residing at Olcott, in the county of Kanawha and State of West Virginia, useful Improvements in Valves, the following is a specification. I f

This invention relates to valves and more particularly to throttle valves.

The object of the invention 'is the provision of a novel valve rod which is provided with a projection thereon providing two valve surfacesl so that when one surface is worn the valve rod may be reversed to bring the other valve surface in position to act upon the seat.

A. further object of the invention is the provision of a valve rod which is reciprocally and rotatably mounted in the casing and which is provided with means whereby the same may be rotated to bring the valve therein in true engagement with the seat while under steam pressure and Without disconnecting the operating'means.

Further objects of the invention will appear as thel following specific description is read in connection with the accompanying of which drawings which form a partof this application, and in which:

Figure 1 is a side elevation. Fig. 2 is a longitudinal section. Fig. 3 is a top plan view. Fig. 4 is a detail elevation showing the inner side of one half of the casing with the valve rod and valves mounted therein.

Referring more particularlyto the drawm, 1 represents the casing which is provi ed with cylindrical nipples 3 and 4 ex ternally threaded at 5 to receive the nuts 6 to reinforce the same and internally threaded at 7 to receivethe pipes 12 and 14. The casing is provided with a floor or partition 10 which has the circular opening 11 in its steam pipe 14 connected to the outlet 4.

The upper and lowercylindrical ends of the have threaded therein glands 16 and 17 w ich have secured to their outer ends the stuffing boxes 18 and 19. The gland 17 has a considerably longer sleeve than the gland 16 and is adapted to enter the casing a considerable distance for a purpose which vwill hereinafter be described.

Slidably mounted in the glands and stuifing boxes is a valve rod 20 havingits ends have invented new and squared as at 21 and provided with grooves 22 adjacent the squared portion for a urpose which will hereinafter be descrl ed. Secured to the valve rod intermediate its length is an enlargement having oppositely dlsposed valve surfaces 23 and 24, each adapted to engage certain sides of the partition 10 when the valve 'rod is operated. The partition is shown as having up er and lower surfaces a and b, the former o which ls'adapted to be engaged by the valve surface 23 and the latter is adapted to be engaged by a valve surface 24 when the valve rod is reversed as will be hereinafter described.

Secured to opposite sides of the casing are the standard tables 25 which are grooved on their outer faces as at 26 to receive the standards 27 and 28, the latter of whichis separated into two parts which are pivoted together as at 29 and the upper part is pivotally connected to the operating lever 30 which travels over a rack segment 31 carried by the standard 27. The segment is slotted at 32 and a headed pin 33 is carried by the lever 30 and travels in'the slot so as to support the handle end of the lever and maintain the same in proper osition so that the latching dog 34 will e held in position to engage the teeth of the segment.

Pivotally mounted upon either side of the lever 30 are arms 35 which have inwardly turned lower ends A36 which have semi-cylindrical sockets 37 to engage the grooves 22 in the valve rod 20 so that the valve rod may be turned therein. When it is desired to reverse the valve stem the packing glands are removed and the arms 35 are disconnected from the end of the valve rod. The valvecasing is then disconnected from the pipes and given a half turn horizontally so as to connect the nipple 3 with the pipe 14. The casing is then inverted or given a half turn on the axis of the pipes so as to bring the valve surface b uppermost and so that the steam will pass from the pipe 12 down through the partition. The valve rod vis then completely reversed so as to bring .the valves may be turned upon their seats while steam presure is upon the valve'and thus the valves are caused. to secure a true seat. l 0 A plunger head 8 operates 1n a socket 9 yformed in the gland 17 so as to cushion the action of the valve in seating and unseating and prevents luttering. f

. Havin thus described the invention, what is claime is- 1.A valve having' a rotatable and re ip-` rocating valve rod, means whereby the same may be'reversed, and means 'whereb the rod a mounte therei, a lever for reciprocating `the valve rod 1n either Egsition, and means' `rotated' in either whereby 'the same may position. l

3, A valve comprising a casing, arod reciprocatively-and rotatively mounted,there in, a double'face valve upon said valve rod,

means whereby'either face of A'the valve may be employed 'to close .the passage through the valve casing, a lever for operating the valve in either sition, and means for rotating the valve 1n eithersposition.

4. A valve 'comprising a casing having a valve seat therem, a valve rod passln through the seat and rotatably mounte therein, means to `-retate the valve rod, means for reversing the valvel rod, and means for reciprocating the same in either position. A r

5. A valve comprising a casing, a `reversible rod slidably and rotatably mounted therein, means for 'reversing theY valve rod,- and means for reciprocating and rotatingthe valve rod in either 'osit-ion,

In testimony'whereo I aix my ,signature inpresence* of two witnesses.
